Hi,
I had similar problems when I was in college. What to do about the summer time? What I did was found a T/pdoc (who in the end wasn't able to provide what I needed but that is another story.) who would see me over the summer. My T from during the year and I planned out what I was going to specifically work on during the summer with this T. In my case since I was moving home to an abusive environment it was working on ways to be safe and find ways to get out of my parents house when I could. This planned issue that I was going to work on made it easier for me to see someone for a short time without having to open up everything I was dealing with because we knew it was going to be for a short time. We had a focus that allowed me to get what I needed in the time frame avaliable. I did know that I was going back to my previous T though. If you do this and find you really like this T and want to continue with him/her then you could defenitetly open up more with more issues etc. This way you would go in with a specific plan for the summer. I don't really know what to suggest about next school year, but I hope that it works out the best for you. And I hope my post made sense.
